Description
Technical Field
The invention belongs to the field of fuel cells, and particularly relates to a sectional type fuel cell clamp.
Background
Fuel cells have become a promising power fixture due to their advantages of zero emissions, long endurance, and high energy conversion efficiency, but the durability of their components and the high cost of materials have been the direction to be further improved. The reactant concentration distribution on the membrane electrode is fanned in the direction of the parallel flow channel inlet and outlet of the fuel cell. The current density on the membrane electrode is not uniform due to the inconsistent mass transfer rate on the uniformly distributed catalytic layer caused by the mismatch of the mass transfer rate and the reaction rate. As the reaction proceeds, the amount of cathode water produced is also affected by the non-uniform current density, which is very likely to cause flooding in some areas. The distribution of the catalyst can affect the difference in water content at different locations. In addition, the saturated vapor pressure of water changes along with the change of temperature, and the uniform temperature rising mode of the fuel cell ensures that the relative humidity inside the flow channel cannot reach 100% at the same time, thereby influencing the concentration of liquid water in the porous electrode.
The uniform catalyst distribution not only cannot be reasonably utilized but also results in an increase in the cost of the membrane electrode. A single heating temperature also tends to cause inconsistencies in the water content of the film. The above are two problems in terms of high cost and durability of the fuel cell.
Traditional laboratory fuel cell fixtures are dominated by single cells and stacks. The monocell has a fine and small flow channel structure, is generally used for researching the characteristics of the membrane electrode, such as catalyst materials, loading capacity and operation condition control, and has a relatively accurate and reliable data result. Compared with single cells, the data measured by the stack has more practical application value, but the experimental cost of the fuel cell stack using a large number of membrane electrodes is very high. The research of the gradient distribution and gradient temperature of the catalyst used for the fuel cell clamp by the existing single cell and the electric pile has certain limitations.
